As part of the popular Then and Now Series, Pittsburgh is celebrated with archival photographs shown alongside specially commissioned contemporary images of the same scene. We find that the evolution of Pittsburgh over the last century has produced a compact urban landscape of older buildings blended with more recent architectural development. Downtown, the office blocks are still punctuated by traces of Pittsburgh"s industrial heritage-the so-called "sliver" warehouses-mingling with the conveniences of modern city life. Over 100 photographs are featured in this amazing view of a fascinating city.
